Provided is a ferritic stainless steel sheet which exhibits excellent cleanability, anti-glare properties, and hydrophilicity. In this ferritic stainless steel sheet, which is temper rolled using a dull roll after being subjected to finishing cold rolling and bright annealing, the steel sheet surface has an arithmetic average roughness Ra in a direction orthogonal to the rolling direction of at least 0.2 µm, but not more than 1.2 µm. Furthermore, the dull-pattern transfer rate to the steel sheet surface is at least 15%, but not more than 70%. Moreover, micropits which are formed in the steel sheet surface, have a depth of at least 0.5 µm, and have an opening area of at least 10 µm2, have a presence density of not more than 10.0 per 0.01 mm2, and an opening area ratio of not more than 1.0%. Furthermore, a film formed on the steel sheet surface is formed from an oxide which mainly consists of SiO2, includes, as film-forming elements other than C, at least Si, N, Al, Mn, Cr, Fe, Nb, Ti, and O, has a Si content of at least 10 atomic%, and has a N content of not more than 10 atomic%. |
